<p>
    在本步骤中，架构概念验证是根据评估条件进行测试的：执行该操作的方式取决于概念验证的形式。例如，如果是可执行原型，这就可能是通过演示来进行的；如果是概念模型，就是通过检查和推理；或者如果是模仿，要求用来自评估条件的输入数据来设置并运行模仿模型，那么就是通过从模型输出的数据的收集和分析。

<p>
    评价评估结果，以确定在架构上有重要意义的需求能否满足，并检查那些需求的有效性。在发展阶段的这个时期，需求仍然是可以更改的，而且项目干系人不一定很好地了解这些需求；例如，可能还有机会减少架构概念验证评估为高风险的需求。所有这些途径都应该在评价结果时被充分探索
    － 这与后面的“精化”和“构造”阶段中的情况形成了对比，在这两个阶段中，更改或重新解释需求的意愿会小得多。评价后，因为项目干系人对范围和可行性有了更好的了解，所以就准备对“商业理由”、“愿景”和“风险列表”的变更提议（如果必要的话）。

<p>
    除了上述事项，回答以下问题可能也会有帮助：
</p>
<ul>
    <li>
        原型与其原始目标和预期的进度安排相比如何？
    </li>
    <li>
        原型设计与架构基线相比较如何？
    </li>
    <li>
        对项目风险（无论是否通过原型直接解决）的新理解是什么？
    </li>
</ul>
